DePuy Orthopedics, a division of Johnson & Johnson, has recalled the ASR XL Acetabular System, a prosthesis used in total hip replacements. Approximately 93,000 of the defective prostheses have been implanted. The failure rate is extraordinarily high because of the metal-on-metal surface, which releases microscopic metal particles into the body. Some patients have had reactions to these particles, such as pain, swelling, and loosening of the prosthesis.
Now DePuy Orthopedics is trying to gather evidence directly from physicians about their patients. Physicians are being asked to obtain medical authorizations from their patients which will allow the physicians to release medical information directly to the manufacturer of the defective product.
